Describe the bug
Just got the extended version yesterday. Seems I am missing the added tooltip thing that has the options to talk/inspect etc NPCs and such. Didn't know I was missing anything until I started watching tutorial videos and they kept using that bar and I,..... didn't have it.

I found this out when at the same step in a tutorial, they had the tooltip, yet I did not.

Expected behavior
I'd like to figure out what's going on that it's not coming up...

Version of the add-on:
Total RP 3 1.5.4 (build 64)

Did you try having Total RP 3 as the only enabled addon and everything else (especially something like ElvUI) disabled?
Yes tried that.

Issue for Extended and not TRP3. You need an active campaign and an NPC targeted to see the actions, though this is something we're looking to improve :
